This hybrid turbo is designed for the Honda Civic 1.7 CDTI with 100 hp, manufactured from 2001 onwards. Its modification includes, in particular, a high-flow MFS compressor wheel, a 360° bearing stop and high-speed balancing.
Three levels of tuning are documented. The modifications become progressively more extensive, starting with the compressor wheel, then the casing d the inlet, and finally the turbine section.
This modification primarily affects the compressor section in order d to adjust the compression capacity and air flow rate d whilst maintaining the specified Installation without modification.
The oversizing of the impeller here requires the intake casing to be re-profiled d. This combination aims to adapt the air passage d to the dimensions of the new impeller without specifying a particular final power output.
This version combines the compressor modifications with a turbine impeller oversized and a re-profiled turbine housing. Such a configuration can alter flow rate and response time; its behaviour depends on the overall engine set-up.
A hybrid turbo retains an architecture suited to the vehicle in question whilst incorporating internal modifications. Depending on the upgrade stage, these may involve the compressor wheel, the housings, the turbine wheel, the thrust bearing and balancing.
The aim is d to adapt the turbocharger’s compression capacity and air flow rate d. A hybrid turbo is therefore not defined solely by the appearance of its compressor wheel, but by the consistency of its geometry and mechanical modifications.
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This technology primarily describes a manufacturing process and does not, on its own, guarantee an increase in air flow d.
A standard MFS impeller may retain a geometry equivalent to that of the original d. A Performance MFS impeller may adopt a geometry adapted to the modification, for example in terms of the profile, height, width or diameter of the blades, provided these modifications are documented.
A standard MFS impeller can be just as glossy as an MFS impeller Performance. It is not its appearance that determines its performance, but its geometry and its ability to move more d'air. The impeller described here is made of forged aluminium; it is lighter, larger and taller than the d'original, with a claimed 15 per cent increase in compression capacity.
The compressor impeller draws in and then compresses the air sent to the engine. Its diameter, profile, height, width and the arrangement of its blades influence its aerodynamic behaviour. A suitable geometry can move more d air under certain conditions, but the result also depends on the casings, the turbine, the boost pressure and the engine management system. A larger impeller does not automatically guarantee better performance and may alter the response time.
The documented 360° thrust bearing distributes axial forces over a wide surface area. It helps the bearing adapt to operating stresses without making the turbocharger insensitive to lubrication or assembly faults.
The rotor is balanced at high speed, up to 150,000 rpm, on a Cimat VSR test bench. This process aims to minimise vibrations and mechanical stresses in the rotating assembly.
Appropriate engine management is required for to make the most of the hybrid turbo’s characteristics. Map settings, boost pressure, fuel injection, exhaust and cooling must be checked or adjusted according to the modification. The wastegate must be adjusted during the ECU remapping. The clutch, the gearbox and other vehicle components must also be checked depending on the level of modification. Fitting this turbo alone does not guarantee a power increase.
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault. Check the lubrication circuit, the oil supply and return d as well as the cleanliness of all pipes.
Check the inlet for any foreign objects. Carry out priming in accordance with the applicable recommendations and follow the manufacturer’s instructions.
A lubrication fault that is not rectified may lead to the turbocharger failing again.
Check the part number marked on the original turbo d and compare it with the OEM and manufacturer part numbers in this datasheet. Also check the make, model, engine type 1.7 CDTI, the power output (100 hp ) and the production period (. ). An identical engine specification is not always sufficient to confirm compatibility.
⚠️ Check your turbo’s part numbers
Before ordering, compare the part number marked on your original turbo d with the part numbers listed in this data sheet. An identical engine specification does not always guarantee compatibility.
If you are unsure about the identification or fitment, please contact us before ordering.

View new turbochargers →A standard exchange turbo allows you to replace a turbocharger whilst returning the old part where a deposit is required. Our catalogue includes numerous part numbers for from various makes and engine types.
View standard exchange turbochargers →Hybrid turbos are designed for set-ups requiring greater air flow d and higher performance potential than a standard set-up. Specifications depend on the turbo, its tuning and the engine configuration.
View hybrid turbos →The turbo Cartridge, also known as the central turbo cartridge, comprises the main rotating components of the turbocharger. ALFI TURBO has over 6,000 Cartridge for turbo part numbers.
View turbo Cartridge →Our catalogue covers a wide range of d applications fitted with d a turbocharged engine.
A single engine type may have been fitted with several different turbochargers depending on theYear, power output, engine version or technical evolution.. The application alone is therefore not always sufficient for to accurately identify the correct turbo.
Before ordering, note down the part numbers shown on the identification plate d of your old turbocharger. This may be d an OEM part number or d a part number from the turbo manufacturer.
Compare these part numbers with those listed on our product pages.. If in doubt, our team can help you verify the part number you are looking for before you place your order.
A loss of power, an unusual whistling noise, oil consumption d, abnormal smoke or poor engine performance may be linked to a turbocharger fault.
However, a fault that appears to be turbo-related may also stem d from a lubrication issue, d from contaminated oil, d from a foreign object, from the intake or exhaust systems, or d from another engine peripheral component.
It is therefore important to investigate the cause of the fault before fitting a new turbo or a new Cartridge.
Since 2012, ALFI TURBO has been assisting private individuals and professionals in identifying and replacing turbochargers.
A turbocharger failure may be the result d of another engine problem. Before fitting d a new turbo or Cartridge, identify and rectify the cause of the original fault to d avoid d damaging the new part.
